Background: Methamphetamine is a highly addictive psychostimulant. Narcotics also reduce anxiety and aggression and create a kind of euphoria. These characteristics provide a special attraction for the abuse of these substances for sexual behaviors, and by that, high-risk sexual behaviors. Objectives: The current research intended to compare the impact of methamphetamine and narcotics on sexual high-risk behaviors. Patients and Methods: This comparative study was performed on 91 men (49 amphetamine abusers and 42 narcotics abusers) from the patients of Yareegar Clinic in Tehran, Iran, within 2019 - 2021. A substance-influenced sexual behavior questionnaire was used to collect the data. Data were analyzed using the analysis of variance. Results: The results showed that the use of amphetamine and narcotics was significantly effective in sexual desire, function, and sexual pleasure (P < 0.001). The investigation of behaviors in the two groups showed significant differences between the two groups in increasing sexual desire, sexual pleasure, desire for sex in anonymous situations, and intimacy and eroticism in a relationship and reducing the negative emotional consequences of sexual behavior (P < 0.001). Conclusions: The use of amphetamines can provide a vicious cycle of arousal-desire by desire and intensification of sexual behaviors, thereby increasing the likelihood of the occurrence and spread of infectious disorders, a phenomenon that is also observed in the use of narcotics. By training sexual skills and making individuals more efficient and cognitive, they can be prevented from entering the aforementioned cycle.

Background: Mastectomy can change body image and affect the sexual activities of patients. Breast reconstruction is a way to reduce the sexual damage caused by mastectomy. Objectives: The present study aimed to compare body image and body exposure during sexual activity and sexual assertiveness among mastectomized women with/without mammaplasty and patients with cancer who volunteered for mammoplasty. Methods: This causal-comparative study was performed on the statistical population of mastectomized women with/without mammaplasty and patients who volunteered for mammoplasty within the age range of 25 - 55 years in Tehran, Iran, in 2018. The sample consisted of 37 women with mastectomy, 28 mastectomized women who volunteered for mammoplasty, and 31 women who underwent mammaplasty after mastectomy. The subjects were selected through convenience sampling in Tehran. All participants were asked to complete the Assessment of Body-Image Cognitive Distortions Questionnaire, the Body Exposure during Sexual Activities Questionnaire, and the Hurlbert Index of Sexual Assertiveness. The data were analyzed by analysis of variance using version 20th of SPSS software. Results: In terms of body-image cognitive distortions, there was no difference between the three groups. The women who underwent mammaplasty had less body exposure during sexual activity than patients who volunteered for mammoplasty (P < 0.01); however, there was no difference between the mastectomized patients and patients who underwent mammaplasty. Exposure to the body or anxious attentional focus on the body during sexual activity was reported frequently less in mastectomized women than in mammaplasty volunteers (P < 0.01). The sexual assertiveness of women who underwent reconstructive surgery was more than mastectomized women and volunteer patients for reconstructive surgery (P < 0.01). The mastectomized group had more sexual assertiveness than patients who volunteered for mammoplasty (P < 0.01). Conclusions: The results support the hypothesis that the issue of body image and its relationship with different aspects of sexual function is complex and requires considering different personality traits and factors as moderators. The importance that a woman places on the breast as a symbol of femininity and sexuality is one of the aforementioned factors. The purpose of reconstruction from the patient’s point of view and the importance that a woman gives to her appearance are other components that should be considered before proceeding with mammoplasty.
